Agentwake knows when your unattended work is done.

The three-hour run that died at minute four

You kick off a three-hour agent run, close the lid, and the Mac goes to sleep at minute four. So you prop the lid open with a book and leave the machine running warm all night for a job that finished at 1 AM. Keep-awake apps hold the Mac awake; none of them knows when the work is done.

How it knows: hooks, a process fallback, and a fail-safe

Agentwake installs a tiny activity hook into each coding tool with one click (nine tools built in, custom agents supported), and falls back to process detection for tools without hooks. Every session reports a heartbeat; when the last one goes quiet, the work is done. The design is fail-safe: a missed signal lets the Mac sleep. It never gets stuck awake.

Prefer to wire it yourself? This is the whole hook, ready to paste into Claude Code’s ~/.claude/settings.json. After an app update the installed hook refreshes itself, so it always matches the current version:

{
  "hooks": {
    "PostToolUse":      [{ "matcher": ".*", "hooks": [{ "type": "command", "command": "mkdir -p ~/.agentwake && touch ~/.agentwake/heartbeat", "async": true, "timeout": 1 }] }],
    "UserPromptSubmit": [{ "hooks": [{ "type": "command", "command": "mkdir -p ~/.agentwake && touch ~/.agentwake/heartbeat", "async": true, "timeout": 1 }] }],
    "SessionEnd":       [{ "hooks": [{ "type": "command", "command": "rm -f ~/.agentwake/heartbeat", "async": true, "timeout": 1 }] }]
  }
}

Everything in Free, everything in Pro

The signal is free. The reaction is paid.

The finish line: what happens when the work ends

Keep-awake gets your run to the end. End-of-session automations decide what happens the moment it stops: pick a trigger, pick the actions, and Agentwake runs them while you are away from the desk.

The flagship case: your agent goes idle for twenty minutes, Agentwake sends a notification, runs your cleanup Shortcut, and puts the Mac to sleep. You come back to finished work and a cool, sleeping machine.

Triggers

• Your AI agent goes idle. The heartbeat goes stale past the timeout, so Agentwake treats the run as finished.
• The keep-awake cap expires. The maximum-duration timer you set runs out.
• A schedule window closes. A weekly or one-shot keep-awake window ends on its own.

Actions, in order

Every sequence opens with a countdown you can cancel, from ten seconds to five minutes. Move the mouse, press a key, or click Cancel and nothing runs. If your agent picks the work back up, the countdown cancels itself. A failed step never blocks the others, only one sequence runs at a time, and the Alerts log records every run.

The Amphetamine alternative for AI agents, compared honestly

Amphetamine is excellent and free, and it deserves its reputation. But like every mainstream keep-awake app it has no idea what your agents are doing. Two newer tools do: Adrafinil (free, macOS 26.4+ only) and Agent Caffeine ($9). A third, Vigil (free, macOS 13+), does not detect agents either, but it goes further than Amphetamine on scheduling, profiles, and session history. Here is the honest picture, feature by feature, sources checked July 2026. If you're looking at Agentwake as an Adrafinil alternative, an Agent Caffeine alternative, or a Vigil alternative, the table below has the facts, not the pitch.

The mainstream field, briefly: KeepingYouAwake (free, MIT), Caffeinated ($3.99), and Lungo ($4) are manual on/off tools. None of the three detects agents, schedules natively, runs end-of-session actions, or supports a closed lid without an external display.

Where Agentwake stands alone in this table: end-of-session action chains, the agent notifications suite, the dashboard with billing and token cost, an alerts log tied to AI-agent events, a thermal guard that pauses and resumes, configurable battery guards (cutoff percentage and only-while-charging, not a fixed threshold), and the free cleaning lock.

No telemetry. The only network calls Agentwake makes are Sparkle update checks, license validation, and the pricing-table refresh you trigger yourself. Agentwake was formerly known as CleanKey.
